1 Introduction

1.1 Background

The Shatin to Central Link (SCL) is one of the railway projects recommended for implementation in Railway Development Strategy 2000. It is an integral component of the expanded rail network, which will be required to support the economic, social and population growth of the HKSAR in the coming years. In particular, it will support the urban renewal of the existing Kowloon City District, planned Kai Tak Development (KTD) and further developments in North East New Territories (including Ma On Shan) by providing direct and efficient rail service between Shatin and the Central Business District of the Hong Kong Island via KTD.

The SCL is also one of the ten large-scale infrastructure projects announced by the Chief Executive in his 2007-2008 Policy Address. According to updated information, SCL is targeted to commence construction by mid 2012. For the purposes of the Environmental Impact Assessment (EIA), five EIA Studies have been conducted to cover different sections of the SCL. They include:

· SCL – Tai Wai to Hung Hom Section [SCL (TAW-HUH)] (hereinafter referred to as “the Project”, being considered in this EIA) – the extension of Ma On Shan Line from Tai Wai Station via Hing Keng, Diamond Hill, Kai Tak, To Kwa Wan, Ma Tau Wai and Ho Man Tin to Hung Hom, and link up with the existing West Rail Line, along with a proposed stabling sidings option in Diamond Hill (DHS)¹;.

· SCL – Mong Kok East to Hung Hom Section [SCL (MKK-HUH)] – the realignment work for the existing East Rail Line tracks from the tunnel portal near Oi Man Estate (Portal 1A) to the proposed North Ventilation Building (NOV) in Hung Hom;

· SCL – Hung Hom to Admiralty Section [SCL (HUH-ADM)] – the section from NOV, Plant Rooms and Emergency Access in Hung Hom across the harbour to the Causeway Bay Typhoon Shelter (CBTS), Exhibition Station (EXH) and then to ADM;

· SCL Protection works at Causeway Bay Typhoon Shelter – the section of approximately 160m long of the SCL tunnel protection works at the crossing over Central-Wan Chai Bypass (CWB) tunnels, which would be constructed under the CWB project; and

· SCL – Stabling Sidings at Hung Hom Freight Yard [SCL (HHS)] – another stabling sidings option for SCL (TAW – HUH) proposed at the former freight yard in Hung Hom^[1].

The proposed tentative alignment of SCL (TAW-HUH) is shown in Figure 1.1 and the tentative locations of off-site works areas (e.g. office, general storage), off-site works sites (e.g. barging facilities, magazine sites etc) are shown in Figure 1.2.

1.2 Purposes of the Manual

The purposes of this Environmental Monitoring and Audit (EM&A) Manual are to:

· Guide the set up of an EM&A programme to ensure compliance with the EIA recommendations;

· Specify the requirements for monitoring equipment;

2 Project Description

2.1 General Alignment

The SCL (TAW-HUH) is an approximately 11km long extension of the Ma On Shan Line (MOL) from Tai Wai through new stations, including Hin Keng Station (HIK), Diamond Hill Station (DIH), Kai Tak Station (KAT), To Kwa Wan Station (TKW), Ma Tau Wai Station (MTW), Ho Man Tin Station (HOM) and connects the West Rail Line at Hung Hom Station (HUH). Most of the sections would be underground except for a section at Hin Keng, and another section at Hung Hom, where the alignments need to be raised and linked with the Ma On Shan Line (MOL) and the West Rail Line respectively to form a strategic east-west rail corridor. The underground sections of the alignment would be constructed by various construction methods including drill-and-blast, cut-&-cover, bored tunnelling, and mined method. Open cut/ cut-&-cover method will be employed for the tunnel portals at Hin Keng and Hung Hom North Fan area, and most of the stations and ventilation building structures, etc.

DIH will become an interchange station with the existing Kwun Tong Line (KTL). The SCL (TAW – HUH) will interchange with the Kwun Tong Line Extension (KTE) and the SCL (MKK-HUH) at HOM and HUH respectively. The HOM and HUH are part of other Designated Projects to be separately implemented.

A new train stabling sidings option will be located at the Diamond Hill CDA site (i.e. former Tai Hom Village) to provide stabling facilities and to allow effective train launching to meet the service requirements.

The SCL (TAW-HUH) will also form an important part of the proposed KTD, providing mass transit service not only to the proposed new commercial and residential developments in the area, but also the Multi-Purpose Stadium Complex and other leisure facilities planned at Kai Tak.

The proposed tentative alignment is shown in Figure 1.1 and the tentative locations of off-site works areas (e.g. office, general storage, barging facilities, magazine sites etc.) are shown in Figure 1.2. A broad description of different sections of the alignment is given below.

2.1.1 Tai Wai to Diamond Hill

The SCL (TAW-HUH) departs from the existing MOL at south of Tai Wai Depot. Leaving the Tai Wai Depot, the track would maintain on embankment and connect to HIK which is an elevated station.

After departing from HIK with a section of viaduct and embankment, the alignment then heads towards the Hin Keng portal at the west of Hin Keng Estate. Once into the portal, the alignment runs under the Lion Rock. There would not be any at-grade construction activities within the Lion Rock Country Park and all the tunnel construction activities would be within the granite layer. The vertical alignment and construction method have also been specially designed to totally avoid Tei Lung Hau Stream and the secondary woodland in Tai Wai.

From the Lion Rock Country Park, the alignment runs towards Ma Chai Hang and Wong Tai Sin. The SCL (TAW – HUH) would interface with the existing KTL at DIH located directly below Lung Cheung Road. SCL (TAW – HUH) passengers would be able to interchange with KTL at this station.

A train stabling sidings would be constructed in the former Tai Hom Village south of DIH.

2.1.2 Diamond Hill to To Kwa Wan

After leaving the DIH, the SCL (TAW-HUH) runs adjacent to the Tate’s Cairn Viaduct and crosses Prince Edward Road East to reach KAT within the Kai Tak Development area, currently a vacant site but with planned future residential and commercial developments.

The alignment runs towards southwest and enters TKW near Sung Wong Toi Garden.

2.1.3 To Kwa Wan to Hung Hom

The alignment runs below Ma Tau Chung Road/ Ma Tau Wai Road towards west and reaches MTW. The areas along Ma Tau Chung Road/ Ma Tau Wai Road comprise high density of multi-storey buildings, including residential, commercial and industrial buildings.

After leaving MTW, the alignment passes Ko Shan Road and joins HOM at the intersection of Fat Kwong Street and Shun Yung Street. HOM, to be implemented by other Designated Project, is also an interchange station at which passengers can interchange between SCL (TAW – HUH) and KTE.

After leaving HOM, the alignment runs below the Winslow Street underpass and the Chatham Road North embankment and then passes through the HUH portal adjacent to Sai Sing Funeral Parlour. Out of the HUH portal, the alignment runs at-grade and heads to HUH.

The tracks for SCL (TAW-HUH) within extension of the HUH area would be at-grade and would eventually join the existing West Rail Line (WRL) tunnel near to the junction of Salisbury Road and Science Museum Road.

The SCL (TAW-HUH) would interface with the SCL (MKK-HUH) and SCL (HUH-ADM) at new HUH to be implemented by other Designated Project. Passengers would be able to interchange at this station.

The HUH would be entirely under the existing podium deck.

2.1.4 Vertical Alignment

As discussed in Section 2.1.1 to 2.1.3, the alignment will run through different areas in Tai Wai, Wong Tai Sin, Diamond Hill, Kai Tak, To Kwa Wan and Hung Hom. Most of these areas are relatively flat terrains except for the areas in Lion Rock and Chuk Yuen.

Notes:

[1] The HOM would be implemented under the KTE and The HUH would be implemented under the SCL (MKK-HUH). Their cumulative impacts have been addressed in the EIA to fulfil the requirements of the EIA study Brief.

2.3 Implementation Programme

According to the latest programme, the construction works for SCL (TAW-HUH) would commence in 2012. All major civil contracts would be completed by 2016. The remaining station fit-out, track layout etc works would be completed by 2018. This would however be subject to changes during the on-going design process.

Detailed EIA assessments have been conducted and presented in the EIA report. Mitigation measures have also been identified and recommended. The Environmental Mitigation Implementation Schedule (EMIS) is given in Appendix A. It specifies the extent, locations, time frame and responsibilities for the implementation of the environmental mitigation measures identified.

4 Cultural Heritage

4.1 Introduction

A cultural and heritage impact assessment for the Project has been conducted according to the EIA Study Brief. The assessment has considered both the construction and operational phases of the project.

The assessment has recommended some mitigation measures for both the archaeological sites and some of the historical buildings where impacts would be envisaged.

4.2 Mitigation Measures

All the proposed mitigation measures are presented below and summarised in the EMIS in Appendix A. Appropriate vibration monitoring on the built heritages will be agreed with Buildings Department (BD)/Geotechnical Engineering Office (GEO) and implemented under the requirement of the Buildings Ordinance and/or Blasting Permit.

4.2.1 Former Tai Hom Village

Previous studies at the former Tai Hom Village Site reveal that the Tang/ Song Dynasty remains found are both sparse and redepositied and hence of lesser archaeological significance. However, assemblage of Tang/ Song archaeological finds within urban setting is considered rare in Hong Kong. It is therefore recommended that a survey-cum-excavation works to be conducted prior to the construction works at the former Tai Hom Village site. The tentative extent for the survey-cum-excavation within former Tai Hom Village is shown in Figure 4.1. Before the excavation, the archaeologist shall conduct further test pits to refine the actual demarcation of the excavation area. The locations and total numbers of these test pits would need to be determined by the archaeologist and agreed with AMO on-site during the survey-cum-excavation.

An Archaeological Action Plan (AAP) following the Guideline for Archaeological Impact Assessment should be submitted to the Antiquities and Monuments Office (AMO) for agreement. The project proponent should appoint qualified and experienced archaeologist(s) with sufficient funding, time and personnel arrangements to implement the AAP. The AAP should include a detailed plan for the survey-cum-excavation and a contingency plan to address possible arrangement if significant archaeological findings are unearthed during the survey-cum-excavation. Details of the proposal plan with specification for the survey-cum-excavation should be agreed with AMO prior to the submission of licence application.

The Former Royal Air Force Hangar, the Old Pillbox and the Stone House No. 4 would be directly affected by the construction of the DHS and SCL-DIH. As detailed photographic and cartographic recorded will be recommended to document the Hangar, Old Pillbox and the Stone House prior to their removal, no other mitigation measure is required during the operational phase of the SCL. The Old Pillbox would be reinstated as far as practicable after being temporarily stored during the construction period. Portions of the hangar frame would also be stored during construction and placed in areas of the CDA site during operational stage to illustrate the structural technology used during war time. A model to represent the current form of the hangar will also be displayed to demonstrate the form and function of the hangar. The project proponent shall submit a separate Conservation Plan for these 3 historical buildings.

4.2.2 Sacred Hill (North Area)

The archaeological investigation by CEDD has verified the archaeological potential of the north of the Sacred Hill. Various evidences suggest that the area was utilized as a burial or living ground, and then turned into a dumping area after the inhabitants left the area. The study also concluded that the artifact density in the area to the east, south and north is low. Since the existing site for the Sacred Hill (North) Area had undergone a series of reclamation over the past few decades, it is anticipated that the archaeological potential for the fill material would be low and only the original top soil layer is considered to have potential for archaeology. The survey-cum-excavation would be limited to the original soil layer within temporary excavation areas within the Sacred Hill (North) Study Area. The exact extent of survey-cum-excavation will be subject to the construction details of the TKW. The tentative area requiring survey-cum-excavation is shown in Figure 4.2. The exact area of rescue excavation would be demarcated subject to the findings of the survey/investigation within the Sacred Hill (North) Study Area.

An Archaeological Action Plan (AAP) following the Guideline for Archaeological Impact Assessment should be submitted to the Antiquities and Monuments Office (AMO) for agreement. The project proponent should appoint qualified and experienced archaeologist(s) with sufficient funding, time and personnel arrangements to implement the AAP. The AAP should include a detailed plan for the survey-cum-excavation, additional boreholes/trenches investigation and a contingency plan to address possible arrangement if significant archaeological findings are unearthed. Details of the proposal plan with specification for the survey-cum-excavation and additional boreholes/trenches investigation should be agreed with AMO prior to the submission of licence application.

4.2.3 Lung Tsun Stone Bridge and Former Kowloon City Pier

Potential direct impact on the Lung Tsun Stone Bridge and Former Kowloon City Pier has been avoided by tunneling underneath them and by adopting a construction method which consolidates and reinforces the soil during works. For Lung Tsun Stone Bridge, a horizontal buffer distance would be maintained. For Former Kowloon City Pier, a vertical separation distance of 1.8-2.2m from the top of the tunnel would be maintained.

4.3 Monitoring and Audit Requirements

According to the EIA, differential movements within the remnants of the Lung Tsun Stone Bridge and Former Kowloon City Pier will be slight. A buffer zone shall be maintained during the construction period as shown in Figure 4.3.

The project proponent should ensure that vibration levels are controlled to appropriate level. Vibration monitoring should be carried out by the contractor. The structures would require monitoring during the construction phase including Wong Tai Sin Temple, S.K.H. Holy Trinity Church and Old Fast East Flying Training School.

5 Ecology

5.1 Introduction

The EIA Report has assessed the ecologcial impacts during construction and operational phases. Mitigation measures have been recommended to ensure compliance of relevant legislative requirements. The mitigation measures and ecological monitoring and audit are given in the sections below.

5.2 Mitigation Measures

5.2.1 Habitat Loss

A detailed vegetation survey should be conducted in the Hin Keng Portal areas to locate and enumerate individuals of Aquilaria sinensis which will potentially be affected by construction and operation of the Portal.

A suitable site for transplanting all affected individuals within the footprint area should be identified and assessed for its suitability. A transplantation plan should then be drawn up and details of the transplantation methodologies and programme along with post-transplantation monitoring should be included.

5.2.2 Tree Felling and Vegetation Clearance

Breeding pairs of Little Ringed Plover, Zitting Cisticola and Plain Prinia were observed in the tall grassland and at the fringes of the old Kai Tak runway. Nesting birds would be impacted by tree felling and vegetation removal including cutting of grassland. Precautionary checks of the vegetation for the presence of nesting bird species of conservation interest should be carried out before vegetation clearance by a suitably experienced ecologist.

5.2.3 Relocation of Bat Tree

Chinese Fan Palms (Livistona chinensis) within the Project Site may be utilized by Short-nosed Fruit Bats. A few no. of trees at DIH will need to be relocated to an adjacent area prior to construction works (see Figure 5.1).

Any individuals of Chinese Fan Palms that would need to be relocated due to the proposed works should be checked for the presence of Fruit Bat roosting.

5.2.4 Water Quality and Hydrology

Indirect water impact to any wetland habitats, such as streams and coastal habitats, or wetland fauna should be avoided by implementing water pollution control measures and good site practices (ETWB TCW No. 5/2005, Protection of natural streams/ rivers from adverse impacts arising from construction works to avoid direct or indirect impacts on the Tei Lung Hau Stream).

5.2.5 Others

Other mitigation measures are summarised in the EMIS in Appendix A.

5.3 Audit Requirements

To check that the recommended mitigation measures are properly implemented, weekly site audits should be conducted by the ET during construction phase of the Project.

6 Landscape & Visual Impact

6.1 Introduction

The EIA has recommended landscape and visual mitigation measures to be undertaken during both the construction and operational phases of the project. The design, implementation and maintenance of landscape mitigation measures should be checked to ensure that any potential conflicts between the proposed landscape measures and any other works of the project would be resolved as early as practical without affecting the implementation of the mitigation measures.

6.2 Mitigation Measures

The proposed mitigation measures of landscape and visual impacts are summarised in the EMIS in Appendix A. The landscape and visual mitigation measures proposed should be incorporated in the detailed landscape and engineering design. The construction phase mitigation measures should be adopted from the commencement of construction and should be in place throughout the entire construction period. Mitigation measures for the operational phase should be adopted during the detailed design and be built as part of the construction works so that they are in place on commissioning of the Project.

6.3 Audit Requirement

Site audits should be undertaken during the construction phase of the Project to check that the proposed landscape and visual mitigation measures are properly implemented and maintained as per their intended objectives. Site inspections should be undertaken by the ET at least once every two weeks during the construction period.

In the event of non-compliance, the responsibilities of the relevant parties are detailed in the Event/Action plan provided in Table 6.1.

7 Air Quality

7.1 Introduction

The EIA has considered the potential air quality impacts during both the construction and operational phases of the Project. Fugitive dust would be the key impacts during the construction phases during which excavation, material handling etc would need to be conducted. Impacts during operational phases are unlikely due to the use of electric train system.

7.2 Mitigation Measures

All the proposed mitigation measures for controlling fugitive dust during the construction phase are summarised in the EMIS in Appendix A. These mitigation measures include the following:

· Mitigation measures in form of regular watering under a good site practice should be adopted. In accordance with the “Control of Open Fugitive Dust Sources” (USEPA AP-42), watering once per hour on exposed worksites and haul road in Kowloon area and once per 1.5 hour at those in Tai Wai area are proposed;

· For the unloading of spoil from trucks at barging point, installation of 3-sided screen with top cover and the provision of water sprays at the discharge point would be provided for an assumed 50% dust suppression.; and

· Any excavated or stockpile of dusty material should be covered entirely by impervious sheeting or sprayed with water to maintain the entire surface wet and then removed or backfilled or reinstated where practicable within 24 hours of the excavation or unloading

7.3 Air Quality Parameters

The levels of total suspended particulate (TSP) should be measured by following the standard method as set out in the High Volume Method for Total Suspended Particulates, Part 50 Chapter 1 Appendix B, Title 40 of the Code of Federal Regulations of the USEPA (the HVS method) or by direct reading methods which are capable of producing comparable results as that by the high volume sampling method.

Dust laden in air should be drawn through a high volume sampler (HVS) fitted with a conditioned, pre-weighed filter paper, at a controlled rate. After sampling for 24-hours, the filter paper with the retained dust particles should be collected and returned to the laboratory for drying in a desiccator followed by weighing. The 24-hour average TSP levels should be calculated from the ratio of the mass of particulates retained on the filter paper to the total volume of air sampled.

All relevant data including temperature, pressure, weather conditions, elapsed-time meter reading for the start and stop of the sampler, identification and weight of the filter paper, and any other local atmospheric factors affecting or affected by site conditions, etc., shall be recorded down in detail. A sample data sheet is shown in Appendix C.

7.4 Monitoring Equipment

High volume samplers (HVSs) complying with the following specifications shall be used for carrying out the 1-hour and 24-hour TSP monitoring:

a) 0.6 - 1.7 m³ per minute adjustable flow range;

b) equipped with a timing / control device with +/- 5 minutes accuracy for 24 hours operation;

c) installed with elapsed-time meter with +/- 2 minutes accuracy for 24 hours operation;

d) capable of providing a minimum exposed area of 406 cm²;

e) flow control accuracy: +/- 2.5% deviation over 24-hour sampling period;

f) equipped with a shelter to protect the filter and sampler;

g) incorporated with an electronic mass flow rate controller or other equivalent devices;

h) equipped with a flow recorder for continuous monitoring;

i) provided with a peaked roof inlet;

j) incorporated with a manometer;

k) able to hold and seal the filter paper to the sampler housing at horizontal position;

l) easily changeable filter; and

m) capable of operating continuously for a 24-hour period.

The ET is responsible for the provision, installation, operation, maintenance, dismantle of the monitoring equipment. They shall ensure that sufficient number of HVSs with an appropriate calibration kit is available for carrying out the baseline monitoring, regular impact monitoring and ad hoc monitoring. The HVSs shall be equipped with an electronic mass flow controller and be calibrated against a traceable standard at regular intervals. All the equipment, calibration kit, filter papers, etc., shall be clearly labelled.

Initial calibration of dust monitoring equipment shall be conducted upon installation and thereafter in every six months. The transfer standard shall be traceable to the internationally recognised primary standard and be calibrated annually. The concern parties such as IEC shall properly document the calibration data for future reference. All the data should be converted into standard temperature and pressure condition.

The flow-rate of the sampler before and after the sampling exercise with the filter in position shall be verified to be constant and be recorded in the data sheet as mentioned in Appendix C.

If the ET Leader proposes to use a direct reading dust meter to measure TSP levels, he shall submit sufficient information to the IEC to prove that the instrument is capable of achieving a comparable result as that the HVS and can be used for sampling. The instrument shall be calibrated regularly following the requirements specified by the equipment manufacturers.

Wind data monitoring equipment shall also be provided and set up for logging wind speed and wind direction near the dust monitoring locations. The equipment installation location shall be proposed by the ET and agreed with the IEC.

7.5 Laboratory Measurement / Analysis

A clean laboratory with constant temperature and humidity control, and equipped with necessary measuring and conditioning instruments to handle the dust samples collected, shall be available for sample analysis, and equipment calibration and maintenance.  The laboratory should be HOKLAS accredited.

If a site laboratory is set up or a non-HOKLAS accredited laboratory is hired for carrying out the laboratory analysis, the laboratory equipment shall be approved by the ER and the measurement procedures shall be audited by the IEC. Any measurement performed by the laboratory shall be demonstrated to the satisfaction of the ER and IEC. IEC shall regularly audit the measurement performed by the laboratory to ensure the accuracy of measurement results.  The ET Leader shall provide the ER with one copy of the Title 40 of the Code of Federal Regulations, Chapter 1 (Part 50), for his reference.

Filter paper of size 8" x 10" shall be labelled before sampling. It shall be a clean filter paper with no pinholes, and shall be conditioned in a humidity-controlled chamber for over 24-hours and be pre-weighed before use for the sampling.

After sampling, the filter paper loaded with dust shall be kept in a clean and tightly sealed plastic bag. The filter paper shall then be returned to the laboratory for reconditioning in the humidity-controlled chamber followed by accurate weighing by an electronic balance with readout down to 0.1 mg. The balance shall be regularly calibrated against a traceable standard.

All the collected samples shall be kept in a good condition for 6 months before disposal.

7.6 Monitoring Locations

Figures 7.1.1 to 7.1.7 show the locations of the proposed construction dust monitoring station. The status and locations of sensitive receivers may change after issuing this manual. If such cases exist, the ET shall propose updated monitoring locations based on criteria below and seek approval from ER and agreement from the IEC and EPD.

Note:

[1] - Same monitoring location under SCL(HHS)

[2] - Dust monitoring will be carried out under SCL (MKK-HUH)

When alternative monitoring locations are proposed, the proposed site should, as far as practicable:

a) be at the site boundary or such locations close to the major dust emission source;

b) be close to the sensitive receptors; and

c) take into account the prevailing meteorological conditions.

The ET shall agree with the ER in consultation with the IEC on the position of the HVS for the installation of the monitoring equipment. When positioning the samplers, the following points shall be noted:

a) a horizontal platform with appropriate support to secure the samplers against gusty wind should be provided;

b) no two samplers should be placed less than 2 m apart;

c) the distance between the sampler and an obstacle, such as buildings, must be at least twice the height that the obstacle protrudes above the sampler;

d) a minimum of 2 m of separation from walls, parapets and penthouses is required for rooftop samplers;

e) a minimum of 2 m separation from any supporting structure, measured horizontally is required;

f) no furnace or incinerator flue is nearby;

g) airflow around the sampler is unrestricted;

h) the sampler is more than 20 m from the dripline;

i) any wire fence and gate, to protect the sampler, should not cause any obstruction during monitoring;

j) permission must be obtained to set up the samplers and to obtain access to the monitoring stations; and

k) a secured supply of electricity is needed to operate the samplers.

7.7 Baseline Monitoring

Baseline monitoring shall be carried out at all of the designated monitoring locations (see Table 7.1) for at least 14 consecutive days prior to the commissioning of major construction works to obtain 1-hour and 24-hour TSP samples. General meteorological conditions (wind speed, direction and precipitation) and notes regarding any significant adjacent dust producing sources shall also be recorded throughout the baseline monitoring period. The selected baseline monitoring stations should reflect baseline conditions at the impact stations. 1-hour TSP sampling should also be done at least 3 times per day.

During the baseline monitoring, there should not be any major construction or dust generation activities in the vicinity of the monitoring stations. Before commencing baseline monitoring, the ET shall inform the IEC of the baseline monitoring programme such that, if required, the IEC can conduct on-site audit to ensure accuracy of the baseline monitoring results.

In case the baseline monitoring cannot be carried out at the designated monitoring locations, the ET shall propose and carry out the monitoring at alternative locations that can effectively represent the baseline conditions at the impact monitoring locations. The alternative baseline monitoring locations shall be approved by the ER and agreed with the IEC.

In exceptional cases, when insufficient baseline monitoring data or questionable results are obtained, the ET shall liaise with the IEC and EPD to agree on an appropriate set of data to be used as a baseline reference and submit to ER for approval.

If the ET considers that significant changes in the ambient conditions have arisen, a repeat of the baseline monitoring may be carried out to update the baseline levels and air quality criteria, after consultation and agreement with the ER, the IEC and the EPD.  

A summary of the requirements for the baseline dust monitoring is shown in Table 7.2.

Table 7.2 Summary of Baseline Dust Monitoring Programme

Monitoring Period	Duration	Parameter	Frequency
Baseline Monitoring	14 consecutive days prior to commencement of major construction works	1-hour TSP	3 times per day
		Continuous 24-hour TSP	Daily

7.8 Impact Monitoring

The ET shall carry out impact monitoring during the entire construction period. For 24-hour TSP impact monitoring, the sampling frequency shall be at least once in every 6 days at each of the monitoring station. 1-hour TSP monitoring shall be conducted when one documented valid complaint is received. The sampling frequency of 1-hour TSP monitoring shall be at least 3 times in every 6 days when the highest dust impacts are likely to occur. Before commencing impact monitoring, the ET shall inform the IEC of the impact monitoring programme such that the IEC can conduct on-site audit to ensure accuracy of the monitoring results.

The specific time to start and stop the 24-hour TSP monitoring shall be clearly defined for each location and be strictly followed by the ET.

In case of non-compliance with the air quality criteria, more frequent monitoring, as specified in the Action Plan in the following section, shall be conducted within the specified timeframe after the result is obtained. This additional monitoring shall be continued until the excessive dust emission or the deterioration in air quality is rectified, and agreed with the ER and the IEC.

A summary of the requirements for the dust impact monitoring is shown in Table 7.3.

Table 7.3 Summary of construction dust monitoring programme

Monitoring Period	Duration	Parameter	Frequency
Impact Monitoring	Throughout the construction period ^[1]	24-hour TSP ^[2]	Once per 6 days

Note [1] 1- hour TSP shall be conducted when one documented valid complaint is received.

[2] 24-hour TSP shall be conducted when project-related construction activities are being undertaken within a radius of 500m from monitoring stations.

7.9 Action / Limit Levels

The baseline monitoring results form the basis for determining the air quality criteria for the impact monitoring. The ET shall compare the impact monitoring results with air quality criteria set up for 24-hour TSP and 1-hour TSP. Table 7.4 shows the air quality criteria, namely Action and Limit levels to be used.

Table 7.4 Action / Limit Levels for Air Quality

Parameters	Action	Limit
24-hour TSP Level in mg m^-3	For baseline level £ 200 mg m^-3, Action level = (baseline level * 1.3 + Limit level)/2; For baseline level > 200 mg m^-3 Action level = Limit level	260mg/m^3
1-hour TSP Level in mg m^-3	For baseline level £ 384 mg m^-3, Action level = (baseline level * 1.3 + Limit level)/2; For baseline level > 384 mg m^-3, Action level = Limit level	500mg/m^3

8 Airborne Noise

8.1 Introduction

The EIA has considered the potential airborne noise impacts during both the construction and operational phases of the Project. Construction noise from mechanical equipment would be the key impacts during the construction phases during which excavation, material handling etc would need to be conducted. Trains running on viaduct and embankment sections would also affect the neighbouring sensitive receivers.

8.2 Mitigation Measures

8.2.1 Construction Phase

All the proposed mitigation measures for controlling airborne construction noise and operational noise are summarised in the EMIS in Appendix A. These mitigation measures include the following:

· Use of good site practices to limit noise emissions;

· Install temporary hoarding located on the site boundaries between noisy construction activities and NSRs;

· Install movable noise barriers, acoustic mat or full enclosure, screen the noisy plants including air compressor, generators, saw;

· Select “Quiet plants” which comply with the BS 5228 Part 1 or TM standards;

· Sequencing operation of construction plants where practicable;

· Implement a noise monitoring under EM&A programme;

· Louvres should be orientated away from adjacent NSRs, preferably onto main roads which are less sensitive;

· Direct noise mitigation measures including silencers, acoustic louvers and acoustic enclosures should be allowed for in the design for the ventilation building, stations and stabling sidings; and

· The facade for these plant areas / ventilation shafts should have adequate sound insulation properties to minimise the noise emanating through the building fabric.

8.2.2 Operational Phase

A series of noise barriers and noise cover would need to be implemented along the tracks between HIK and Tai Wai Station in order to mitigate the train noise impacts. These mitigation measures include the following and are shown in Figures 8.1.1 – 8.1.2:

· Approx. 350m of noise barrier at a height 2m from the down track level of SCL (TAW-HUH) (P1);

· Approx. 100m of noise barrier at a height 2m from the up track level of SCL (TAW-HUH) (P2);

· Approx. 150m of noise barrier at a height 3m from the up track level of SCL (TAW-HUH) (P3);

· Approx. 300m of noise barrier at a height 7m from the tail track level T2 of TAW (P4); and

· Approx. 50m of noise barrier at a height 3m from the down track level of SCL (TAW-HUH) (P5)

· Approx. 15m noise cover at the south-west of TAW near Mei Tin Road.

8.3 Noise Monitoring Parameters

Construction noise level shall be measured in terms of the A-weighted equivalent continuous sound pressure level (L_eq). L_{eq 30 min} shall be used as the monitoring parameter for the time period between 0700 and 1900 hours on normal weekdays.

As supplementary information for data auditing, statistical results such as L₁₀ and L₉₀ shall also be obtained for reference.

8.4 Monitoring Equipment

As referred to in the Technical Memorandum (TM) issued under the NCO, sound level meters in compliance with the International Electrotechnical Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type 1) specifications shall be used for carrying out the noise monitoring. Immediately prior to and following each noise measurement, the accuracy of the sound level meter shall be checked using an acoustic calibrator generating a known sound pressure level at a known frequency. Measurements may be accepted as valid only if the calibration level before and after the noise measurement agrees to within 1.0 dB.

Noise measurements should be made in accordance with standard acoustical principles and practices in relation to weather conditions.

The ET is responsible for the provision, installation, operation, maintenance, dismantle of the monitoring equipment. He shall ensure that sufficient noise measuring equipment and associated instrumentation are available for carrying out the baseline monitoring, regular impact monitoring and ad hoc monitoring. All the equipment and associated instrumentation shall be clearly labelled.

8.5 Monitoring Locations for Construction Phase

The locations of construction noise monitoring stations are summarised in Table 8.1 and shown in Figures 8.2.1 to 8.2.6.

NMS-CA-11	HUH-1-3	Wing Fung Building^[1]

Note:

[1] - Same monitoring location under SCL(HHS)

When alternative monitoring locations are proposed, the monitoring locations should be chosen based on the following criteria:

· at locations close to the major site activities which are likely to have noise impacts;

· close to the most affected existing noise sensitive receivers; and

· for monitoring locations located in the vicinity of the sensitive receivers, care should be taken to cause minimal disturbance to the occupants during monitoring.

In case the baseline monitoring cannot be carried out at the designated monitoring locations, the ET shall propose and carry out the monitoring at alternative locations that can effectively represent the baseline conditions at the impact monitoring locations. The alternative baseline monitoring locations shall be approved by the ER and agreed with the IEC and EPD.

The monitoring station shall normally be at a point 1m from the exterior of the sensitive receiver building facade and be at a position 1.2 m above local ground. If there is problem with access to the normal monitoring position, an alternative position may be chosen, and a correction to the measurements shall be made. For reference, a facade correction of +3 dB(A) shall be made to the free field measurements. The ET shall agree with the IEC and EPD on the monitoring position and the corrections adopted. Once the positions for the monitoring stations are chosen, the baseline monitoring and the impact monitoring shall be carried out at the same positions. If changes to the monitoring stations are required upon the baseline monitoring, the ET should propose alternative locations based on the above-mentioned criteria and seek approval from the ER and agreement from the IEC and EPD on the proposal.

8.6 Baseline Monitoring for Construction Phase

The ET shall carry out baseline noise monitoring prior to the commencement of the construction works. There shall not be any construction activities in the vicinity of the stations during the baseline monitoring. Continuous baseline noise monitoring for the A-weighted levels L_eq, L₁₀ and L₉₀ shall be carried out daily for a period of at least two weeks in a sample period of 30 minutes between 0700 and 1900 hrs and 15 minutes (as three consecutive L_{eq,(5 minutes)} readings) for evening time (between 1900 and 2300 hours on normal weekdays), general holidays including Sundays (between 0700 and 2300 hours) and night-time (between 2300 and 0700 on all days). Before commencing baseline monitoring, the ET shall inform the IEC of the baseline monitoring programme such that, if required, the IEC can conduct on-site audit to ensure accuracy of the baseline monitoring results.

In exceptional cases, when insufficient baseline monitoring data or questionable results are obtained, the ET shall liaise with the IEC and EPD to agree on an appropriate set of data to be used as a baseline reference.

8.7 Impact Monitoring for Construction Phase

During normal construction working hour (0700-1900 Monday to Saturday), monitoring of L_{eq, 30min} noise levels (as six consecutive L_{eq, 5min} readings) shall be carried out at the agreed monitoring locations once every week in accordance with the methodology in the TM-EIAO.

For construction monitoring stations at schools, noise monitoring shall be carried out during the school examination periods. The ET shall liaise with the school’s personnel to ascertain the exact dates and times of all examination periods during the course of the contract.

In case of non-compliance with the construction noise criteria, more frequent monitoring, as specified in the Action Plan, shall be carried out. This additional monitoring shall be continued until the recorded noise levels are rectified or proved to be irrelevant to the construction activities.

8.8 Event and Action Plan for Construction Phase

The Action and Limit levels for construction noise are defined in Table 8.2.

Table 8.2 Action and Limit Levels

Time Period	Action Level	Limit Level
0700 - 1900 hours on normal weekdays	When one documented valid complaint is received	75 dB(A) *

Note : If works are to be carried out during restricted hours, the conditions stipulated in the construction noise permit issued by the Noise Control Authority have to be followed.

* Reduce to 70 dB(A) for schools and 65 dB(A) during school examination periods.

To account for cases in which ambient noise levels, as identified by baseline monitoring, approach or exceed the stipulated Limit Levels prior to the commencement of construction, a Maximum Acceptable Impact Level, which incorporates the baseline noise levels and the identified construction noise Limit Level, may be defined and agreed with the EPD. The amended level will be greater than 75 dB(A) and will represent the maximum acceptable noise level at a specific monitoring station. Correction factors for the effects of acoustic screening and/or architectural features of NSRs may also be applied as specified in the Technical Memorandum on Noise from Construction Work other than Percussive Piling (GW-TM).

Should non-compliance of the criteria occur, action in accordance with the Action Plan in Table 8.3 shall be carried out.

8.9 Operation Rail Noise Monitoring

Prior to the operation phase of the Project, a commissioning test will be conducted for verification of EIA predictions against the assessment goals and checking the compliance of the airborne noise levels with the NCO noise criteria.

Monitoring of L_eq,30min train noise levels will be carried out at the proposed monitoring locations during night-time period, i.e.2300-0700 on a monthly basis after SCL (TAW-HUH) is in operation. Background noise levels shall also be measured. It is recommended to conduct the monitoring for the initial start-up of up to 6 months. With full compliance of the noise limit and agreement from IEC, monitoring can be terminated before the end of this 6-month period.

8.10 Monitoring Equipment and Methodology

The monitoring equipments and methodology for operation rail noise monitoring should be same as those recommended for construction noise monitoring.

8.11 Noise Monitoring Stations

Based on the EIA study, the potentially worst affected locations were designated for operational airborne noise monitoring as listed in Table 8.4 and illustrated in Figures 8.3.1-8.3.2.

Table 8.4 Monitoring Stations during Operation Phase

ID	NSR ID in EIA	Location
NMS-OA-1	TAW-P1-2	Festival City
NMS-OA-2	HUH-1-3	Wing Fung Building^[1]

Note:

[1] - Same monitoring location under SCL(HHS)

The status and location of noise monitoring stations may change after approval of this Manual. In such cases, and if changes to the monitoring locations are considered necessary, the ET Leader should propose updated monitoring stations and seek agreement from the IEC and EPD on the proposal. If alternative monitoring locations are proposed, the monitoring locations should be chosen based on the following criteria:

· Monitoring at NSRs close to the major operation activities which are likely to cause train induced noise impacts;

· Monitoring as close as practicable to the NSRs as defined in the EIAO-TM and IND-TM; and

· Assurance of minimal disturbance to the occupants and working under a safe condition during monitoring.

The monitoring stations should normally be at a point 1m from the exterior of the noise sensitive facade and be at a position 1.2m above ground. If there is a problem with access to the normal monitoring position, an alternative position should be chosen, and a correction to the measurements should be made. For reference, a correction of +3dB(A) should be made to the free field measurements. The ET Leader should agree with the IEC on the monitoring position and the corrections adopted.

9 Groundborne Noise

9.1 Introduction

Prediction of construction groundborne noise indicates the criteria will be achieved and mitigation measures are not required. In order to ensure proper control of groundborne noise, a noise commissioning test should be conducted by the ET at the proposed groundborne noise monitoring stations (see Table 9.2 below) prior to the operation of the Project to confirm the compliance of the operational groundborne noise levels with the NCO noise criteria.

9.2 Mitigation Measures

Since all the predicted groundborne noise impacts comply with the legislative requirements, no mitigation measures are required for construction and operational phases ground-borne noise. Prior to the operation phase of the Project, commissioning test will be conducted to ensure compliance of operation groundborne noise levels with the TM-EIAO relevant noise criteria.

9.3 Groundborne Noise Monitoring Parameters and Criteria

The operational groundborne noise criteria for the representative NSRs along SCL (TAW–HUH) alignment are tabulated in Table 9.1 below.

Table 9.1: Operational groundborne noise criteria

Domestic premises along alignment	B	55	45	45
	C	60	50	50

Notes: [1] These NSRs are considered to be noise sensitive during daytime and evening time only.

9.4 Monitoring Equipment

As referred to in the Technical Memorandum (TM) issued under the NCO, sound level meters in compliance with the International Electrotechnical Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type 1) specifications shall be used for carrying out the groundborne noise monitoring. Immediately prior to and following each noise measurement, the accuracy of the sound level meter shall be checked using an acoustic calibrator generating a known sound pressure level at a known frequency. Measurements may be accepted as valid only if the calibration level before and after the noise measurement agrees to within 1.0 dB.

The ET is responsible for the provision, installation, operation, maintenance, dismantle of the monitoring equipment. He shall ensure that sufficient noise measuring equipment and associated instrumentation are available for carrying out the baseline monitoring, regular impact monitoring and ad hoc monitoring. All the equipment and associated instrumentation shall be clearly labelled.

9.5 Monitoring Locations

The proposed groundborne noise monitoring stations for commissioning test are summarised in Table 9.2 and shown in Figures 9.1.1 to 9.1.3.

Table 9.2 Proposed groundborne noise monitoring stations for commissioning test

ID	NSR ID in EIA	Description

NMS-OG-2	MTW-6-2	Hong Kong Society for the Protection of Children
NMS-OG-3	HOM-1-1	Ko Shan Theatre
NMS-OG-4	HUH-1-3	Wing Fung Building^[1]

Note:

[1] - Same monitoring location under SCL(HHS)

The monitoring station shall normally be at the lowest sensitive floor of each designated monitoring location and normally be at a position 1.2 m above ground inside the building structures. The monitoring locations shall also not be significantly affected by background noise level. The exact locations for the monitoring shall be proposed by the ET and agreed with IEC and EPD.

If there is problem with access to the normal monitoring position, an alternative position may be chosen, and a correction to the measurements shall be made. The ET shall agree with the IEC on the monitoring position and the corrections adopted. Once the positions for the monitoring stations are chosen, the baseline monitoring and the impact monitoring shall be carried out at the same positions. If changes to the monitoring stations are required upon the baseline monitoring or thereafter, the ET should proposed alternative locations based on the above-mentioned criteria and seek approval from the ER and agreement from the IEC and EPD on the proposal.

9.6 Baseline Monitoring

Existing L_eq(30min) levels should be monitored at the monitoring locations without trains running to obtain the ambient noise levels. After the train noise levels are measured (if measured directly), these ambient levels should be deducted from the measured L_eq(30min) levels to obtain the operational noise levels in the absence of ambient noise.

9.7 Impact Monitoring

A noise commissioning test should be conducted by the ET prior to the operation of the Project to confirm the compliance of the operational ground-borne noise levels with the NCO noise criteria. The noise commissioning test should be performed at proposed groundborne noise monitoring locations listed in Table 9.2.

10 Water Quality

10.1 Introduction

The EIA Report has assessed the water quality impacts associated with the Project.. According to the EIA Report, the water quality impact could be minimized with the implementation of mitigation measures. The water quality monitoring programme as discussed below could ensure the implementation of the recommended mitigation measures and provide continue improvements to the environmental conditions.

10.2 Mitigation Measures

The EIA Report has recommended construction phase mitigation measures. All the prepared mitigation measures are summarised in the EMIS in Appendix A. The key mitigation measures include the following.

Construction Site Runoff / Site Drainage:

· Construction site runoff and site drainage should be mitigated in accordance with the Practice Note for Professional Persons on Construction Site Drainage, Environmental Protection Department, 1994 (ProPECC PN 1/94).

Tunneling Works:

· Cut-&-cover/ open cut tunnelling work should be conducted sequentially to limit the amount of construction runoff generated from exposed areas during the wet season (April to September) as far as practicable.

· Uncontaminated discharge should pass through sedimentation tanks prior to off-site discharge

· The wastewater with a high concentration of SS should be treated (e.g. by sedimentation tanks with sufficient retention time) before discharge. Oil interceptors would also be required to remove the oil, lubricants and grease from the wastewater.

· Direct discharge of the bentonite slurry (as a result of D-wall and bored tunnelling construction) is not allowed. It should be reconditioned and reused wherever practicable. Temporary storage locations (typically a properly closed warehouse) should be provided on site for any unused bentonite that needs to be transported away after all the related construction activities are completed. The requirements in ProPECC PN 1/94 should be adhered to in the handling and disposal of bentonite slurries.

Construction Sewage Effluent:

· Adequate numbers of portable toilets should be provided for handling the construction sewage generated by the workforce. The portable toilets should be maintained in a reasonable state, which will not deter the workers from utilizing these portable toilets. Overnight sewerage should be collected by licensed collectors regularly.

Groundwater from Contaminated Area:

· No direct discharge of groundwater from contaminated areas should be adopted. Prior to the excavation works within these potentially contaminated areas, the groundwater quality should be reviewed with reference to the site investigation data in the EIA report for compliance to the Technical Memorandum on Standards for Effluents Discharged into Drainage on Sewerage Systems, Inland and Coastal Waters (TM-Water) and the existence of prohibited substance should be confirmed. The review results should be submitted to EPD for examination If the review results indicated that the groundwater to be generated from the excavation works would be contaminated, the contaminated groundwater should be either properly treated in compliance with the requirements of the TM-Water or properly recharged into the ground.

· If wastewater treatment is deployed, the wastewater treatment unit shall deploy suitable treatment process (e.g. oil interceptor / activated carbon) to reduce the pollution level to an acceptable standard and remove any prohibited substances (e.g. TPH) to undetectable range. All treated effluent from wastewater treatment plant shall meet the requirements as stated in TM-Water and should be discharged into the foul sewers.

· If groundwater recharging wells are deployed, recharging wells should be installed as appropriate for recharging the contaminated groundwater back into the ground. The recharging wells should be selected at places where the groundwater quality will not be affected by the recharge operation as indicated in the Section 2.3 of TM-Water. The baseline groundwater quality shall be determined prior to the selection of the recharge wells, and submit a working plan (including the laboratory analytical results showing the quality of groundwater at the proposed recharge location(s) as well as the pollutant levels of groundwater to be recharged) to EPD for agreement. Pollution levels of groundwater to be recharged shall not be higher than pollutant levels of ambient groundwater at the recharge well. Prior to recharge, any prohibited substances such as TPH products should be removed as necessary by installing the petrol interceptor. The Contractor should apply for a discharge licence under the WPCO through the Regional Office of EPD for groundwater recharge operation or discharge of treated groundwater.

Dredging Works:

· Install efficient silt curtains at the point of seawall dredging to control the dispersion of SS;

· Water quality monitoring should be implemented to ensure effective control of water pollution and recommend additional mitigation measures required;

· The decent speed of grabs should be controlled to minimize the seabed impact and to reduce the volume of over-dredging; and

· All vessels should be sized so that adequate clearance is maintained between vessels and the seabed in all tide conditions, to ensure that undue turbidity is not generated by turbulence from vessel movement or propeller wash.

Barging Point:

· All barges should be fitted with tight bottom seals to prevent leakage of materials during transport;

· Barges or hoppers should not be filled to a level that will cause overflow of materials or polluted water during loading or transportation;

· All vessels should be sized so that adequate clearance is maintained between vessels and the seabed in all tide conditions, to ensure that undue turbidity is not generated by turbulence from vessel movement or propeller wash; and

· Loading of barges and hoppers should be controlled to prevent splashing of material into the surrounding water.

To check that the recommend mitigation measures are properly implemented, weekly site audits should be conducted by the ET during construction phase of the Project.

10.3 Monitoring Locations

Water quality monitoring at inshore waters during SCL (TAW–HUH) construction is not required, marine water quality monitoring, however, shall be carried out while dredging activities are conducting.

The water quality monitoring stations and control stations of SCL (TAW–HUH) are shown in Figure 10.1. The co-ordinates of the proposed monitoring stations (construction phase – dredging activities) are listed in Table 10.1. As shown in Figure 10.1, the proposed locations are classified as Impact Station and Control Station according to their functions. The ET shall seek approval from IEC and EPD for any alternative monitoring locations.

Table 10.1 Water quality monitoring stations (construction phase – dredging activities)

Station	Description	Easting	Northing
IS-1	Impact Station for Dredging Activities	838450	819399
CS-1	Control Station for IS-1	838170	818903
CS-2	Control Station for IS-1	838912	818997

10.4 Monitoring Parameters

The monitoring shall normally be established by measuring the Dissolved Oxygen (DO), temperature, turbidity, pH, salinity and Suspended Solids (SS) at all designated locations as specified in Section 10.3 above.

The measurements shall be taken at all designated monitoring stations including control stations, 3 days per week, at mid-flood and mid-ebb tides. Tidal range of individual flood and ebb tides should be not less than 0.5m.

All the monitoring shall be taken at 3 water depths, namely 1m below water surface, mid-depth and 1m above sea bed, except where the water depth less than 6m, the mid-depth station may be omitted. Should the water depth be less than 3m, only the mid-depth station will be monitored.

Replicate in-situ measurements and samples collected from each independent sampling event shall be collected to ensure a robust statistically interpretable database. DO, pH value, salinity, temperature and turbidity should be measured in-situ whereas SS should be determined by an accredited laboratory.

Other relevant data shall also be recorded, including monitoring location/ position, time, water depth, tidal stages, weather conditions and any special phenomena or work underway at the construction site.

10.5 Baseline Monitoring

Baseline conditions for marine water quality shall be established and agreed with EPD prior to the commencement of dredging works. The purpose of the baseline monitoring is to establish ambient conditions prior to the commencement of the dredging works and to demonstrate the suitability of the proposed impact and control monitoring stations.

The baseline monitoring shall be conducted for at least 4 weeks prior to the commencement of dredging works. The proposed water quality monitoring schedule shall be submitted to EPD by the ET at least 2 weeks before the first day of the monitoring month. The interval between two sets of monitoring shall not be less than 36 hours. EPD shall also be notified immediately for any changes in schedule.

There should be no marine work in the vicinity of the stations during the baseline monitoring. The monitoring programme may overlap with other non-project marine activities. The monitoring exercise should be scheduled as far as possible to avoid concurrent dredging / backfilling activities around the monitoring stations such that representative ambient data could be sampled.

As it is likely to have concurrent activities such as dredging works of Proposed Cruise Terminal at Kai Tak, the ET shall seek approval from the IEC and EPD on an appropriate set of data, such as EPD’s routine monitoring data, baseline monitoring data for cruise terminal, etc, to be used with the baseline data collected by this study to establish the Action/ Limit Levels. The determination of Action/Limit Levels will be discussed in Section 10.9.

Table 10.2 summarises the proposed monitoring frequency and water quality parameters for baseline monitoring.

Table 10.2 Proposed water quality monitoring programme

Monitoring Parameters	DO, temperature, turbidity, pH, salinity and SS
Intervals between 2 Sets of Monitoring	Not less than 36 hours
Tide Range	Individual flood and ebb tides not less than 0.5m

10.6 Impact Monitoring

The impact monitoring shall be conducted during dredging period. The purpose of impact monitoring is to ensure the implementation of the recommended mitigation measures, provide effective control of any malpractices, and provide continuous improvements to the environmental conditions. The proposed water quality monitoring schedule shall be submitted to EPD by the ET at least 2 weeks before the first day of the monitoring month. The interval between two sets of monitoring shall not be less than 36 hours. EPD shall also be notified immediately for any changes in schedule.

In case of project-related exceedances of Action and/or Limit Levels, the impact moniotring frequency shall be increased according to the requirement of Event and Action Plan. The details of Event Action Plan will be discussed in Section 10.10.

Table 10.3 summarises the proposed monitoring frequency and water quality parameters for and impact monitoring.

Table 10.3 Proposed water quality monitoring programme

Monitoring Parameters	DO, temperature, turbidity, pH, salinity and SS
Intervals between 2 Sets of Monitoring	Not less than 36 hours
Tide Range	Individual flood and ebb tides not less than 0.5m

10.7 Monitoring Equipments

Dissolved Oxygen and Temperature Measuring Equipment

The dissolved oxygen (DO) measuring instruments should be portable and weatherproof. The equipment should also complete with cable and sensor, and DC power source. It should be capable of measuring:

· a DO level in the range of 0 - 20 mg/L and 0 - 200% saturation; and

· a temperature of 0 - 45 degree Celsius.

The equipment should have a membrane electrode with automatic temperature compensation complete with a cable.

Should salinity compensation not be built-in to the DO equipment, in-situ salinity should be measured to calibrate the DO measuring instruments prior to each measurement.

Turbidity Measuring Equipments

The turbidity measuring instruments should be a portable and weatherproof with DC power source. It should have a photoelectric sensor capable of measuring turbidity level between 0 - 1000 NTU (for example, Hach model 2100P or an approved similar instrument).

Salinity Measuring Equipments

A portable salinometer capable of measuring salinity in the range of 0 - 40 parts per thousand (ppt) should be provided for measuring salinity of the water at each monitoring location.

pH Measuring Equipments

A portable pH meter capable of measuring a pH range between 0.0 and 14.0 shall be provided under the specified conditions (e.g., Orion Model 250A or an approved similar instrument).

Positioning Equipments

A hand-held or boat-fixed type digital Differential Global Positioning System (DGPS) with way point bearing indication and Radio Technical Commission for maritime (RTCM) Type 16 error message ‘screen pop-up’ facilities (for real-time auto-display of error messages and DGPS corrections from the Hong Kong Hydrographic Office), or other equipment instrument of similar accuracy, should be provided and used during marine water monitoring to ensure the monitoring vessel is at the correct location before taking measurements.

Water Depth Detector

A portable, battery-operated echo sounder should be used for water depths determination at each designated monitoring station. The detector can either be hand held or affixed to the bottom of the work boat, if the same vessel is to be used throughout the monitoring programme.

Water Sampler

A water sampler is required for SS monitoring. It should comprise a transparent PVC cylinder, with a capacity of not less than 2 litres, which can be effectively sealed with latex cups at both ends. The sampler should have a positive latching system to keep it open and prevent premature closure until released by a messenger when the sampler is at the selected water depth (for example, Kahlsico Water Sampler or an approved similar instrument).

Sample Containers and Storage

Water samples for SS determinations should be stored in high density polythene bottles with no preservative added, packed in ice (cooled to 4°C without being frozen) and shipment to the testing laboratory. The samples shall be delivered to the laboratory within 24 hours of collection and be analysed as soon as possible after collection.

Calibration of In-Situ Instruments

The pH meter, DO meter and turbidimeter shall be checked and calibrated before use. DO meter and turbidimeter shall be certified by a laboratory accredited under HOKLAS or any other international accreditation scheme, and subsequently re-calibrated at quarterly basis throughout all stages of the water quality monitoring. Responses of sensors and electrodes should be checked with certified standard solutions before each use. Wet bulb calibration for a DO meter shall be carried out before measurement at each monitoring station.

Back-up Equipment and Vessels

Sufficient stocks of spare parts shall be maintained for replacements when necessary. Backup monitoring equipment shall also be made available so that monitoring can proceed uninterrupted even when some equipment is under maintenance, calibration, malfunction, etc.

The water quality monitoring will involve three monitoring stations and measurements should be conducted within the prescribed tidal conditions in order to ensure the measurement/samples are representative. A multi-probe monitoring equipment set integrated with water sampler(s) is highly recommended to improve the monitoring efficiency. Depending on the actually operation, more than one field survey vessels might be required simultaneously to ensure the monitoring are conducted within the acceptable monitoring period. The ET shall also consider the use of unattended automatic sampling/monitoring devices at fixed stations where monitoring are required throughout the construction period. The use of such unattended automatic devices, however, shall be subject to the approval of the ER, IEC and EPD.

10.8 Laboratory Measurement / Analysis

At least 3 replicate samples from each independent sampling event are required for the suspended solids measurement which shall be carried in a HOKLAS or international accredited laboratory. Sufficient water samples shall be collected at the monitoring stations for carrying out the laboratory measurement and analysis. The laboratory determination work shall start within 24 hours after collection of the water samples. The analysis for SS is presented in Table 10.4.

Table 10.4 Laboratory analysis for SS

11 Waste Management

11.1 Introduction

The quantity and timing for the generation of waste during the construction phase have been estimated. Measures including the opportunity for on-site sorting, reusing excavated materials etc, are devised in the construction methodology to minimise the surplus materials to be disposed off-site. Proper disposal of chemical waste should be via a licensed waste collector. All the proposed mitigation measures are stipulated in the EIA Report and summarised in the EMIS in Appendix A.

The types and quantities of waste that would be generated during the operational phase have been assessed. It is anticipated there would not be any insurmountable impacts during the operational phase. A trip-ticket system should be operated to monitor all movements of chemical wastes which will be collected by a licensed collector to a licensed facility for final treatment and disposal. Recommendations have been made to ensure proper treatment and proper disposal of these wastes in the EIA Report and summarised in the EMIS in Appendix A. The mitigation measures should form the basis of the Environmental Management Plan (EMP).

EM&A requirements are required for waste management during the construction phase only and the effective management of waste arising during the construction phase will be monitored through the site audit programme. The aims of the waste audit are:

· to ensure the waste arising from the works are handled, stored, collected, transferred and disposed of in an environmentally acceptable manner; and

· to encourage the reuse and recycling of material.

11.2 Waste EM&A Requirements

The Contractor shall be required to pay attention to the environmental standard and guidelines and carry out appropriate waste management and obtain the relevant licence/permits for waste disposal. The ET shall ensure that the Contractor has obtained from the appropriate authorities the necessary waste disposal permits or licences including:

· Chemical Waste Permits/licenses under the Waste Disposal Ordinance (Cap 354);

· Public Dumping Licence under the Land (Miscellaneous Provisions) Ordinance (Cap 28);

· Marine Dumping Permit under the Dumping at Sea Ordinance (Cap 466); and

· Effluent Discharge Licence under the Water Pollution Control Ordinance.

The Contractor shall refer to the relevant booklets issued by the DEP when applying for the licence/permit and the ET shall refer to these booklets for auditing purposes.

Regular audits and site inspections should be carried out during construction phase by the ET to ensure that the recommended good site practices and other recommended mitigation measures are properly implemented by the Contractor. The audits should concern all aspects of on-site waste management practices including waste generation, storage, recycling, transport and disposal. Apart from site inspection, documents including licences, permits, disposal and recycling records should be reviewed and audited for compliance with the legislation and contract requirements.

The requirements of the environmental audit programme are set out in Section 14 of this Manual. The audit programme will verify the implementation status and evaluate the effectiveness of the mitigation measures.

12 Land Contamination

12.1 Introduction

A land contamination assessment has been conducted and historical information such as site geological information, ground condition, aerial photos have been collated. After consideration of other remediation options, it has been estimated that approximately 39 m³ of soil near the former Tai Hom Village was contaminated and hence need to be properly disposed. Figure 12.1 shows the location of this hot spot.

12.2 Excavation and Disposal Methodology

Prior to commencement of soil remedial works, the area requiring remediation should be clearly marked out on site and the surface levels recorded. Excavation of contaminated material should be undertaken using dedicated earth-moving plant that should be thoroughly cleaned (e.g. jet-washed) following completion of excavation works.

An area extending to 3.5m radius from the sample location should be excavated to the depth given in Figure 12.1 (i.e. a circular area of 7m diameter centred on the drillhole location).

Excavated contaminated soils should not be stockpiled on site, but should immediately be loaded onto trucks and taken to the landfill site. All trucks carrying contaminated material should be adequately covered by sheet to prevent dispersion of contamination during transportation.

Although the contaminated soils is situated above the groundwater table, due to the fluctuation of the groundwater table, the remediation contractor should pay attention to the selection of suitable groundwater lowering schemes and discharge points if the groundwater table is higher than the contaminated soils during excavation. The remediation contractor should also obtain a valid Water Pollution Control Ordinance (WPCO) discharge licence from EPD where applicable.

Given the EPD’s Guidance Notes for Investigation and Remediation of Contaminated Sites of: Petrol Filling Stations, Boatyards and Car Repair/Dismantling Workshops has been superseded by the new Practice Guide (PG) for Investigation and Remediation of Contaminated Land in August 2011, the remediation contractor should carry out the remediation works in accordance with the procedure set out in the new PG and other Ordinance relevant to the works.

The entire remediation programme should be supervised by an on-site Decontamination Specialist (to be appointed by the Contractor), who should have at least 7 years experience in contamination assessment or decontamination. All relevant method statements prepared by the remediation contractor should be reviewed and approved by the Decontamination Specialist before proceeding with the works.

12.3 Compliance Testing

Following completion of excavation to the specified depth, at least one sample from the base of the excavation and three samples evenly distributed along the boundary of the excavation shall be taken for carrying out the compliance testing. The compliance testing requirements are shown in Table 12.1.

Table 12.1 Requirements for compliance testing

Locations	Testing Requirement	Acceptance Criteria
2209/SCL/EDH127	PCBs	RBRGs (Industrial category)

If the analysis indicates continued presence of contamination, the excavation shall be extended a further 0.5m depth or 1m wide with material disposed of as described above, and a further sample taken for compliance testing. The process of excavation, sampling and compliance testing should continue until all contaminated materials are removed. The excavated areas should then be backfilled using suitable clean fill material.

12.4 Protective and Safety Measures

The contaminants present on the site are at relatively low levels, and are not expected to pose serious acute health risk to the site workforce. However, it is good practice to ensure that remediation workers are adequately protected to ensure that there are no significant residual risks. The following health and safety precautions are therefore recommended:

· Personal Protective Equipment (PPE) such as safety hat, chemical protective gloves, masks, eye goggles, protective clothing (upgraded if contact with contaminated material cannot be avoided) and protective footwear etc. must be provided to staff, which would be involved in the remediation work. No works should be allowed without the suitable PPE.

· Workers should inspect and check their PPE before, during and after use. In cases where any of the PPE is broken, the worker shall stop work immediately and inform the on-site registered safety officer. The worker is not allowed to re-start his work until the broken PPE is replaced.

· Hand washing basins or other washing facilities shall be provided in areas easily accessible to all workers.

· Workers should always maintain basic hygiene standard (e.g. hand wash before leaving the contaminated work zone). Workers shall also be responsible for cleaning and storing their own PPE in a secure place before leaving the site.

· Eating, drinking and smoking must be strictly prohibited within the site areas.

It should be noted that these precautions are additional to any other health and safety requirements that will apply on the site such as those requiring protective footwear and headgear.

12.5 Remediation Reports

A Remediation Report (RR) to demonstrate adequate clean-up shall be prepared by the Contractor and submitted to EPD after review/ verification by ER, ET and IEC necessary for endorsement prior to the commencement of any construction/ development works within the sites. No construction/ development works shall be carried out prior to the endorsement of the RR.

13 Hazard to Life

13.1 Introduction

Blasting activities regarding the storage, transport and use of explosives should be supervised and audited by the competent site staff to ensure strict compliance with the blasting permit conditions.

13.2 Mitigation Measures

The recommended mitigation measures as outlined in the EMIS included in Appendix A of this EM&A Manual should be implemented to meet the EIAO-TM requirements.

14 Site Environmental Audit

14.1 Site Inspection

Site inspection provides a direct means to initiate and enforce specified environmental protection and pollution control measures. These shall be undertaken routinely to inspect construction activities in order to ensure that appropriate environmental protection and pollution control mitigation measures are properly implemented. Site inspection is one of the most effective tools to enforce the environmental protection requirements at the works area.

The ET shall be responsible for formulating the environmental site inspection programme as well as the deficiency and action reporting system, and for carrying out the site inspections. The proposal for rectification, if any, should be prepared and submitted to the ET Leader and IEC by the Contractor.

Regular site inspections shall be carried out and led by the ER and attended by the Contractor and ET at least once per week during the construction phase. The areas of inspection shall not be limited to the environmental situation, pollution control and mitigation measures within the site. It should also review the environmental situations outside the works area which is likely to be affected, directly or indirectly, by the construction site activities of the Project. The ET shall make reference to the following information in conducting the inspection. During the inspection, the following information should be referred to:

(i) EIA Report recommendations on environmental protection and pollution control mitigation measures;

(ii) works progress and programme;

(iii) individual works methodology proposals (which shall include the proposal on associated pollution control measures);

(iv) contract specifications on environmental protection;

(v) relevant environmental protection and pollution control legislations; and

(vi) previous site inspection results.

The Contractor shall keep the ER and ET Leader updated with all relevant environmental related information on the construction contract necessary for him to carry out the site inspections. Site inspection results and associated recommendations for improvements to the environmental protection and pollution control efforts should be recorded and followed up by the Contractor in an agreed time-frame. The Contractor shall follow the procedures and time-frame as stipulated in the environmental site inspection, and the deficiency and action reporting system formulated by the ET, to report on any remedial measures subsequent to the site inspections.

The ER, ET and the Contractor should also carry out ad-hoc site inspections if significant environmental problems are identified. Inspections may also be required subsequent to receipt of a valid environmental complaint, or as part of the investigation work, as specified in the Action Plan for the EM&A programme.

14.2 Environmental Compliance

There are statutory requirements on environmental protection and pollution control requirements with which construction activities must comply.

In order that the works comply with all method statements of works should be submitted by the Contractor to the ER for approval and to the ET Leader to ensure sufficient environmental protection and pollution control measures have been included. The Environmental Mitigation Implementation schedule (EMIS) is summarised in Appendix A. Any proposed changes to the mitigation measures shall be certified by the ET Leader and verified by the IEC as conforming to the relevant information and recommendations contained in the EIA Report.

The ER and ET shall also review the progress and programme of the works to check that relevant environmental legislations have not been violated, and that any foreseeable potential for violating laws can be prevented.

The Contractor should provide the update of the relevant documents to the ET Leader so that checking can be carried out. The document shall at least include the updated Works Progress Reports, updated Works Programme, method statements, any application letters for different licences / permits under the environmental protection laws, and copies of all valid licences / permits. The site diary and environmental records shall also be available for inspection by the relevant parties.

After reviewing the document, the ET shall advise the IEC and Contractor of any non-compliance with legislative requirements on environmental protection and pollution control so that they can timely take follow-up actions as appropriate. If the follow-up actions may still result in potential violation of environmental protection and pollution control requirements, the ER and ET should provide further advice to the Contractor to take remedial action to resolve the problem.

Upon receipt of the advice, the Contractor shall undertake immediate actions to correct the situation. The ER and ET shall follow up to ensure that appropriate action has been taken in order to satisfy legal requirements.

14.3 Choice of Construction Method

At times during the construction phase the Contractor may submit method statements for various aspects of construction. This state of affairs would only apply to those construction methods that the EIA has not imposed conditions while for construction methods that have been assessed in the EIA, the Contractor is bound to follow the requirements and recommendations in the EIA study. The Contractor’s options for alternative construction methods may introduce adverse environmental impacts into the Project. It is the responsibility of the Contractor and ET, in accordance with established standards, guidelines and EIA study recommendations and requirements, to review and determine the adequacy of the environmental protection and pollution control measures in the Contractor’s proposal in order to ensure no unacceptable impacts would result. To achieve this end, the ET shall provide a copy of the Proactive Environmental Protection Proforma as shown in Appendix E to the IEC for approval. The IEC should audit the review of the construction method and endorse the proposal on the basis of no adverse environmental impacts.

14.4 Environmental Complaints

The following procedures should be undertaken upon receipt of any environmental complaint:

(i) The Contractor to log complaint and date of receipt onto the complaint database and inform the ER, ET and IEC immediately;

(ii) The Contractor to investigate, with the ER and ET, the complaint to determine its validity, and assess whether the source of the problem is due to construction works of the Project with the support of additional monitoring frequency and stations, if necessary;

(iii) The Contractor to identify remedial measures in consultation with the IEC, ET and ER if a complaint is valid and due to the construction works of the Project;

(iv) The Contractor to implement the remedial measures as required by the ER and to agree with the ET and IEC any additional monitoring frequency and stations, where necessary, for checking the effectiveness of the remedial measures;

(v) The ER, ET and IEC to review the effectiveness of the Contractor's remedial measures and the updated situation;

(vi) The ET to undertake additional monitoring and audit to verify the situation if necessary, and oversee that circumstances leading to the complaint do not recur;

(vii) If the complaint is referred by the EPD, the Contractor to prepare interim report on the status of the complaint investigation and follow-up actions stipulated above, including the details of the remedial measures and additional monitoring identified or already taken, for submission to EPD within the time frame assigned by the EPD; and

(viii) The ET to record the details of the complaint, results of the investigation, subsequent actions taken to address the complaint and updated situation including the effectiveness of the remedial measures, supported by regular and additional monitoring results in the monthly EM&A reports.

15 Reporting

15.1 General

Reports can be provided in an electronic medium upon agreeing the format with the ER and EPD. This would enable a transition from a paper / historic and reactive approach to an electronic / real time proactive approach. All the monitoring data (baseline and impact) shall also be submitted on diskettes or other approved media. The formats for air quality, noise and water quality monitoring data to be submitted shall be separately agreed.

The ET is responsible for establishing and maintaining a dedicated website throughout the entire construction period for publishing all the relevant environmental monitoring data (including but not limited to the baseline and impact monitoring). The ET shall propose the format and functionality of the website for agreement with the ER and IEC prior to publishing of data.
